FAQs
For straightforward installation, select Pneufit C push-in fittings that match the G1/4 port. Cut tubing cleanly, insert the tube squarely into the ferrule until it seats, and verify orientation so air flows in the intended direction. Use compatible 8 mm tubing and ensure clamps or brackets secure the valve in a vibration-free position to prevent movement during operation.
Key specs include a G1/4 port size, aluminium body, operating temperature from -20 to 80 °C, and an operating pressure range of 0.1 to 10 bar. The valve weighs 0.025 kg and has compact dimensions (54 mm length, 18.5 mm width, 18.5 mm height). It is silicone-free and designed for reliable one-way flow in compressed air systems.
Yes. The valve supports unidirectional flow control crucial for protecting actuators and sensors in packaging and automation lines. Its compact aluminium body, low cracking pressure, and silicone-free construction help maintain cleanliness and reliability in fast-paced environments, while its compatibility with Pneufit C fittings simplifies installation in space-constrained panels.
The datasheet indicates emphasis on general industry compliance, with CE-marking being a common expectation for European deployments. For safety-critical or regulated environments, verify the exact CE status and any IP/rated environment suitability with your supplier and project standards before deployment.
The valve’s silicone-free design, compact footprint, and low cracking pressure translate to reduced particulate contamination and easier maintenance. Its simple, robust construction helps minimize downtime, supports longer service intervals, and lowers total cost of ownership in automated lines and versatile pneumatic assemblies.
